方法详细资料

create

public static MergeProcessor create()

Factory method for this processor.

返回:

a new Processor instance

setDataPath

public final void setDataPath(String[] path)

参数:

path - [null is equivalent to an empty array]

setSessionOutFile

public final void setSessionOutFile(String fileName)

NOTE: there is no setter for merge attribute because this processor always overwrites the out file [to ensure compaction]

参数:

fileName - [null unsets the previous override setting]

validateState

protected void validateState()

从类复制的说明: Processor

Validates attribute settings before each Processor._run(IProperties).

Overridden implementations should chain to super.validateState().

覆盖:

validateState 在类中 Processor

_run

protected void _run(IProperties toolProperties)

从类复制的说明: Processor

This method is implemented by each concrete Processor class to perform tool-specific processing.

指定者:

_run 在类中 Processor

参数:

toolProperties - properties incorporating app-global setting and overrides set optionally via Processor.setPropertyOverrides(Properties) or Processor.setPropertyOverrides(IProperties) [never null]
